CARRIER-TRACK.

To all whom it may concern:

Be it known that we, WILLIAM MITCHELL and JOHN F. MITCHELL, citizens ofthe United States, residing in Milwaukee, in the county of Milwaukee andState of Wisconsin, have invented new and useful Improvements inCarrier-Tracks, of which the following is a description, reference beinghad to the accompanying drawings, which are a part of thisspecificationQ This invention relates to improvements in carrier trackswhich are particularly adapted to support carriers which are used inremoving manure or other material from large barns or stables to theoutside of the barn whereby the carrier may be discharged at any pointdesired within certain limits.

A further object of the invention is to provide a carrier track in theform of a crane or boom which is pivotally connected to a barn or otherpermanent support and which is adapted to be swung outwardly therefromat any angle desired.

A further object of the invention is to provide a carrier track of thecharacter described which is provided with a flexible portion toform acurved bend which will permit the travel therearound of the carriers inpassing from the track within the barn to the pivotal track connectedthereto.

A further object of the invention is to form a carrier track of thecharacter de scribed which is so formed, braced and supportedthat alight and very rigid structure is provided. With the above and otherobjects in view, the invention consists of the carrier track andits-parts and combinations as set forth the same reference charactersindicate the same parts in all of the views: Figure 1 is a side view ofthe track shown connected to the side wall of a barn, the barn wallbeing shown in section; Fig. 2 is a plan view of the track; Fig. 3 is atransverse sectional view-on a larger scale of the track taken on line3--3 of Fig. 1. Fig. 4 is a detail View of the supporting rod.

Referring to the drawings the numeral 8 indicates a fragment of the wallof a barn or other buiding and 9 the doorway thereof. A hinge member 10securely bolted to the door frame of the barn is provided with roundedprojectionsll extending in vertical Specification of Letters Patent.

alinement with relation to each other and which are straddled by thefingers 12 extendlng in pairs rearwardly from the tube holding member13. A supporting tube 14:,

the inner end of which is held in the socket of the tube holding member,extends therefrom horizontally the distance desired and the outer endand the medial portions are supported by stay rods or cables 15 and 16respectively. These stay rods or cables are pivotally connected at theirupper ends to an eye bolt 17 fastened to the upper portion of the barnand extend downwardly and outwardly at an angle and at their lower endsare connected to collars 18 and 19 respectively which surround the tube.When the supporting tube is formed of two or more pieces, the ends arecoupled together by a split coupling 20 the half sections of which arebolted together to clamp the tube ends therebetw'een.

The collar 19 is provided with side socketed arms 21 carrying side tubes22 which have notched caps 23 on their outer ends to accommodate trussbrace rods 24. These rods are positioned on each side of the tube andare connected at their inner ends to the tube holding member and attheir outer ends are hooked over the end of the tube, the outer ends ofthe rods being bent to form hooks 25 for that purpose. Turn buckles 26form part of the length of the truss brace rods to provide fortightening said rods to form a rigid structure.

A track 27 consisting of angle iron portions 28 spaced a slight distanceapart and connected together by cross ties 29 is suspended from thesupporting tube by suspension rods 30. These rods which have eyes 31formed on their upper ends through which the tube extends dependdownwardly therefrom and have hook's 32 formed on their lower ends whichhook beneath the cross ties 29 between the angle iron sections. Theinner end of the crane track adjacent to the pivotal connection of thesupporting tube to the hinge member is connected to a fixed trackleading to the interior of the barn by short rail sections 33 which forma flexible track section to permit the swinging of said trackhorizontally in the arc of a circle. These rail sections are pivotallyconnected together and are also pivotally connected to a straight springmember 3 1 to normally hold the track sections in aline-J ment. A setscrew threaded through the tube holding member securely fastens the tubeto'said member.

- From the foregoing description it will be seen that the track isstrong and durable and the construction permits the swinging of thecrane to the right or left and the carrier may travel from the trackwithin the barn to the crane track regardless of the position to whichthe crane has been swung.

What we claim as our invention is:

1. ,A carrier track comprising a hinge member, a supporting memberpivotally connected to the hinge member and extending outwardlytherefrom, supporting means connected to the supporting member andextending upwardly at an angle to a point above the hinge member, staymeans bracing the supporting member laterally, suspension meansdepending from the supporting member, and a track connected to thesuspension means and extending in a line substantially parallel with thesupporting member.

2. A carrier track, comprising a fixed track, a hinge member positionedabove the track, a supporting member pivotally connected to the hingemember and extending outwardly therefrom, stay rods connected to thesupporting member and extending up wardly at an angle to a point abovethe hinge member, suspension means depending from the supporting member,a track connected to the suspension means and extending in a linesubstantially parallel with the supporting member, and a flexible tracksection interposed between and connected to the inner end of thesuspension track and the outer end of the fixed track.

3. A carrier track, comprising a fixed track, a hinge member positionedabove the outer end of the track, a tube holding member pivotallyconnected to the hinge member, a tube connected to and extendingoutwardly from the tube holding member,--stay .rods connected to thetube and extending upwardly at an angle to a point above the hingemember, stay rods bracing the tube laterally, suspension means dependingfrom the tube, a track connected to the suspension means and extendingin a line substantially parallel with the tube, and a flexible tracksection interposed between and connected to the inner end of thesuspension track and the outer end of the fixed track.

4. A carrier track, comprising a fixed track, a hinge member positionedabove the outer end of the track and provided with rounded projectionsextending in vertical alinement with relation to each other, a tubeholding member having fingers which straddle the rounded projections, atube connected to and extending outwardly from the tube holding member,a collar mounted on the tube and having arms extending horizontally atright angles to the tube, stay rods connected to the tube holding memberand to the outer end of the tube and in engagement with the outer endsof the arms, stay rods connectedto the tube and extending upwardly at anangle to a point above the hinge member, rods. extending around the.tube and depending therefrom and vhaving
